Direct measurement of the W boson width.
We present a direct measurement of the width of the W boson using the shape of the transverse mass distribution of W --> enu candidate events. Data from approximately 1 fb(-1) of integrated luminosity recorded at square root of s = 1.96 TeV by the D0 detector at the Fermilab Tevatron pp collider are analyzed. We use the same methods and data sample that were used for our recently published W bo...
متن کاملthe tragedy of modern man in arthur millers world
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
15 صفحه اولThe Mass and Width of the W Boson
The Tevatron and LEP2 experiments presently provide the most precise direct determinations of the mass and width of the W boson. The combined results are : Mw = 80.394 0.042 GeV and ? W = 2.095 0.106 GeV. The results are in excellent agreement with the predictions of the Standard Model. In this article the latest results are described and the systematic errors which could limit further signiica...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولSupersymmetric QCD corrections to the W -boson width
We calculate the one-loop supersymmetric QCD corrections to the width of the W -boson. We find that these are of order ∼ αs π 1 20 M W M S Γud̄, where MS is the supersymmetry breaking scale and Γud̄ the tree level hadronic width for W + → ud̄. Due to the appearance of the suppression factor ∼ 1 20 these are at least two orders of magnitude smaller than the standard QCD corrections ∼ αs π Γud̄ and h...
